Part, drill bushing mounting hole is the position for ensureing fixed drill bushing, and the axis of drill bushing mounting hole should be vertical with bushing plate, it manufactures essence
Degree directly affects the processing quality of subsequent product.
The operation principle of the main frame of wind turbine generator system motor installing hole drill jig of the present invention：
In the process of motor installation screw, drill jig is lifted to the corresponding motor installing hole of wind-driven generator mainframe
In heavy platform, lifting bolt is then shed, plane carries out bore operation on bushing plate by magnetic drill absorption, according to fixed drill bushing
The directly lower drilling in position, after the processing for completing two groups of motor installing holes, drill jig is sling and reinstalls drill jig and carries out other holes
The processing of system.
The beneficial effect of the main frame of wind turbine generator system motor installing hole drill jig of the present invention：
1. the main frame of wind turbine generator system motor installing hole drill jig of the present invention, the design of fixed drill bushing is the bright spot of the frock,
This is because designing the structure of the bushing plate according to the position dimension of two neighboring motor installing hole, hole parallactic angle degree is directly determined
The problem of, it ensure that the positional precision of motor installing hole.
2. the main frame of wind turbine generator system motor installing hole drill jig of the present invention, fixed drill bushing generally can be used 1000~
12000 times, its economy it is clear that and hole positional precision it is also higher, greatly reduce the processing cost of motor installing hole.
3. the present invention main frame of wind turbine generator system motor installing hole drill jig, using the twin opening (subway) in parts to be processed into
Row positioning, by the drill jig, solves the problems, such as that wind driven generator principal gantry motor installation screw can not use machine tooling, and fixed
Position precision is high, using process simply, conveniently, lays the foundation for the batch micro operations of product.
